GEORGE HAlt'rll, OF FAIRFIELD, ASlllNGlON CAR-AXLE.

no. ocioso Application filed. December To all whom it may concern:

Be it known that l, Gnomiz l i. tield. 1n the county et Spokane, Icitate ot l[i'ashiirgton, have invented certain ne f' and usetul improvements in Car-Axles; and l do' hereby declare the toll-owing to be a tull, clear, and exact desrriilition ot the invention, sach as will enable others skilled in thev art to which it appertains to nial';` and use the saine.

This invention relatesl to car axles; has tor its object to provide an axle tor this purpose made in two sections axially disposed with relation to each other and joined by a swivel connection so that the wheels iixed on the outer ends of said axle may rotate independently ol each othe whe in'suuding curves. Ythus enabling the wheel traveling' on the'rail havingv the longer radius. to rotate faster than the other wheel, thereby reducing friction between the wheels and the track to a minimum and causing a saving in power eauired to move the train, lessening the wear on both rails and wheels and thus lengtheningtheir lite.

Vith these and other objects in view, the invention consists in the novel construction, combination and arrangement et parts hereina'lter described and claimed`r and illustrated in the accompanying drawings, in which- Figure l an exterior view of the improved car axle. Fig. Q is a similar view ot the two-part axle with the swivel oonneo tion shown in section. `Fig. is a cross sec tional view on the line 3 3 ot Fig. l. Fig. 4L is a perspective view ot the detail ot the invention.

Similar reference characters are used to indicate the same parts throughoutthe several views.

ln the drawings, the axle is made of two parts. l and 2 each provided with a bearing 3 on its outer end and adapted to be rigidly connected to a wheel (not shownl in the usual manner. The axle members l and 2 are disposed in line with each other and have their inner ends which are tlat and perpendicular to the center or rotation in close relation to each other, one ot said ends, 'for instance that end on the axle section l, being provided with an exterior thread la, on which is firmly secured a sleeve et threaded to tit the end ot the axle and looked thereon against rotation by means of one or more a nd Specification of Letters Patent.

l lf/olts o screwed through the end oi" the sleeve r xian', a citi- Xen oit the United States, resid ng at Fairai bearing tirmly against the threads la on the axle section l. The remainder oit the sleeve -i which is preferably longer than the threaded portion is provided with a bore ot greater diameter than the axle section 2 nich rotates therein 't'or the purpose ot' rebearing boxes or brasses t3, which t troni the inner end ot the shaft secon l nearly to the opposite end oit the rlhe. brasses t3 are made in two parts, each s-enii-circular in cross section and provided near their inner ends with a semi-cirizlar rib l arranged to enter a peripheral ioove ti cut in the. axle section 2, as shown i the drawing.

A collar i) loosely encircles the shaft section and is provided with an exterior taread on one end adapted to engage the threaded outer end of the sleeve et and bear against the ends of the brasses G, forcing them against the shoulder 10, formed by enlarging the bore in said sleeve to titsaid brasses. The friction produced on the brasses by thus clampingl them between the shoulder l0 and collar 9 is Sufficient to prevent said brasses trom rotating in the sleeve and to prevent the latter from loosening or being unscrewed by the rotation o-l the axle, one or more locking bolts ll are threaded through the adjacent end of the sleeve and hear on the threads of the collar. An oil c'up 12 of any approved type is attached to the sleeve Llfor the purpose of lubricating the bearing between the axle and the brasses.

A two-part car axle, constructed as above described, is simple in construction and comprises but few parts which are strong and firmly secured together and afford a relatively long bearing for the inner end of the axle section 2, which rotates in the brasses carried by the sleeve and in the collar 9. rl`he two axle sections are prevented from separating` or having any longitudinal movement with respect to each other by the arrangement ot the brasses G, which are held firmly in the sleeve a by the collar 9, and they in turn, hold the section 2 by means of the ribs 7, engaging the groove 8, from longitudinal play.

llilhat is claimed is:

l. A car axle comprising two independently rotatable alining sections, one ot said sections having a circumferential groove formed in its inner end; a sleeve secured to the other section and inclosing the inner ends of both sections; and a bearing member for the iirst named member disposed within the bore of said sleeve and provided with a projection fitting in said groove.

2. A car axle comprising two independently rotatable alining sections, one of said sections having a circumferential groove formed in its inner end; a sleeve secured to the other section and inclosing the inner ends of both sections; and a boxing disposed within the bore of said sleeve and forming a bearing for the rst named member, said boxing being provided with a projection fitting in said groove.

3. A car axle, comprising two sections in alinement with their ends in juxtaposition, a sleeve secured against rotation to one of said axle sections, a boxing in the opposite end of said sleeve to form a bearing for the inner end of the other axle section, and a collar rotatable on said latter axle section adapted to be secured in the end of the sleeve and bear against said boxing.

4. A car axle, comprising two sections in alinement with their inner ends in close relation to each other, a sleeve screwed on one of said axle sections and having an enlarged bore in its other end, a two-part boxing disposed in said bore and arranged to form a bearing for the other axle section, said boxing having` an inwardly projecting rib engaging a peripheral groove in said latter axle section, and a collar rotatable on said section adapted to be screwed into the end of the sleeve and against the end of the boxing.

A car axle, comprising two sections in alinement with their inner ends being in close relation to each other, a sleeve threading` on the end of one of said axle sections and having its opposite end bored out. to a greater diameter than the axle, brasses adapted to be inserted in said' enlarged bore and having inwardly projecting ribs fitting a circumferential groove in the other axle section, a collar rotatable on said axle section screwed into the outer threaded end of the sleeve and clamping said boxes firmly therein, and bolts threaded through the ends of the sleeve for locking the axle section threaded thereinto and the collar against rotation with respect to said sleeve.

In testimony whereof, I aiiix my signature, in presence of two witnesses.
